How to redirect user to the review tab of the app page on Google Play from a browser?

Here's a hack that works: append &reviewId=0 to the end of the URL.

The reviewId parameter allows you to link to a particular review, but if the review is not found, you simply end up in the "User Reviews" tab.

Example: https://play.google.com/store/apps/details?id=com.cureatr.messenger&reviewId=0
